About Thibault

Hello 👋

I design and develop SaaS platforms and complex web applications, from the first line of code to production.

My main expertise focuses on the Shopify ecosystem, where I transform the needs of e-merchants into high-performing and perfectly integrated applications.
As a co-founder and lead developer of the Elevora application, I recently led it from idea to publication on the Shopify App Store.

How I can help you:
  • **Create your SaaS product or web platform**: Robust architecture, modern stack (React, Next.js, Node.js) and product vision for a scalable result.
  • **Develop your custom Shopify application**: Whether it's a private app or a public app for the App Store, I master the ecosystem (APIs, Polaris, Remix).
  • **Optimize your store**: Development of theme extensions, checkout extensions, and custom integrations.

Looking for a developer who combines strategic vision with sharp technical expertise? Let's discuss your project.
